Leetcode for System Design
- 1SD
Many platforms exist for a candidate to practice leetcode style questions. Created one to practice and discuss system design problem statements.

We’re combining AI-driven mock interviews with community-driven content to create a comprehensive preparation tool for systems design, product, and business interviews.
